Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a resin blowing and filling device for water treatment in oilfield steam injection boilers. Background Technology

[0002] Steam injection boilers play multiple roles in oil extraction, including improving oil recovery, improving well conditions, and reducing costs. By injecting high-pressure steam, steam injection boilers can reduce the viscosity of crude oil, improve its fluidity, and thus increase permeability, enabling more crude oil to be extracted and effectively utilizing oilfield resources.

[0003] During operation, oilfield steam injection boilers require the use of resin blowing devices to treat the water, thereby softening the water and preventing scale buildup in the boiler.

[0004] Publication number CN119118292A discloses a waste heat boiler water softening treatment device, including a tank, with support columns installed at both ends of the bottom of the tank, a cover installed on the top of the tank, a purified water tank installed on the top of the cover, a drain pipe connected to the left end of the bottom of the tank, a sewage pipe connected to the right end of the bottom of the tank, and a stirring assembly disposed in the inner cavity of the tank, including a stirring shaft connected to the inner bottom wall of the tank via bearings, and a driving component disposed at the bottom of the tank, with the top of the driving component connected to the bottom of the stirring shaft.

[0005] This technology may have the drawback of limited stirring effect, as it relies on a single stirring shaft and drive component for stirring. For softening large volumes of water in the tank, uneven stirring may occur, affecting the softening effect. This patent uses air-driven transportation after stirring, which can further improve the mixing effect.

[0006] Announcement No. CN221544282U discloses a water softening device for a steam boiler, including a tank body with a support base at the bottom of the tank body and a discharge port at the bottom of the tank body. The discharge port is equipped with a discharge valve. The device also includes a water distribution mechanism and a regeneration acceleration mechanism based on the water distribution mechanism. The water distribution mechanism includes a water distribution valve and a water distribution pipe, and the regeneration acceleration mechanism includes a drive motor and a propeller body.

[0007] This technology may have limitations in its regeneration acceleration mechanism. Relying on a drive motor and propeller, the acceleration effect on the regeneration process may not be ideal, and it may not be able to quickly and efficiently regenerate ion exchange resins, thus affecting the overall operating efficiency of the device. This patent, by separately setting up a mixer and a resin separator to remove and replace the resin, allows for external regeneration using dedicated regeneration equipment, ensuring the overall operating efficiency of the device.

[0008] Announcement No. CN209567900U discloses a water purifier for reducing scale buildup in industrial boilers, comprising an outer shell, a filtration mechanism disposed within the outer shell, an inlet located at the top center of the filtration mechanism and on the outside of the outer shell, a baffle horizontally disposed below the filtration mechanism and within the outer shell, and ion exchange tanks symmetrically connected to both sides of the bottom of the baffle, the ion exchange tanks being filled with ion exchange resin, and a filter screen disposed at the bottom of the ion exchange tanks.

[0009] This technology has the drawback of filter clogging. The filter screen is easily clogged by impurities in the water during long-term use, which affects the water flow and filtration effect. It needs to be cleaned or replaced regularly, but its structure makes it difficult to clean or replace the filter screen. This patent uses a separate mixer and resin separator, which can clean the filter plate when the resin is removed.

[0010] In summary, the technical solutions, technical problems to be solved, and beneficial effects of the above-disclosed technologies are all different from those of this utility model. For more technical features, technical problems to be solved, and beneficial effects of this utility model, the above-disclosed technical documents do not provide any technical inspiration.

[0012] To achieve the above objectives, the present invention adopts the following technical solution:

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1:

[0039] Please see Figures 1 to 3 The present invention provides a resin blowing and filling device for water treatment of oilfield steam injection boiler, including a base plate 1, on which a mixer and a resin separator are provided, and the mixer and the resin separator are connected by a gas-driven transport pipeline.

[0040] Furthermore, the mixer includes a mixing tank 12, with a discharge pipe 15 at the bottom of the mixing tank 12, which is connected to a pneumatic transport pipeline. A first motor 17 is mounted on the top surface of the mixing tank 12, and the output shaft of the first motor 17 is inserted into the mixing tank 12. The output shaft of the first motor 17 is connected to a rotating shaft 18 via a coupling, and a stirring rod 19 is welded to the outer wall of the rotating shaft 18. A feed hopper 13 is fixedly provided on the top surface of the mixing tank 12, and a water inlet pipe 14 is fixedly provided on the top surface of the mixing tank 12. By pouring resin into the mixing tank 12 from the feed hopper 13, and simultaneously connecting the water inlet pipe 14 to an external water pipe, water can be added to the mixing tank 12. Then, the first motor 17 is turned on, causing the rotating shaft 18 to rotate, which in turn causes the stirring rod 19 to rotate, stirring and mixing the water and resin. This ensures that the water and resin are fully mixed and in complete contact before entering the resin separator, preventing water stratification and improving the water treatment effect.

[0041] Specifically, a support frame 11 is fixedly provided on the top surface of the base plate 1, and a mixing tank 12 is fixedly provided on the top surface of the support frame 11. The discharge pipe 15 passes through the support frame 11.

[0042] Specifically, at least two stirring rods 19 are evenly arranged around the circumference of the rotating shaft 18 to form a stirring rod group, and at least two groups of stirring rods are equidistantly arranged along the axial direction of the rotating shaft 18.

[0043] Furthermore, the resin separator includes a resin tank 3 with an opening at the top, and the pneumatic transport pipeline is connected to the opening at the top of the resin tank 3. The upper outer wall of the resin tank 3 is bolted to a slide rail 31, and a lug 35 is connected inside the slide rail 31 via a linear movement mechanism. The end of the lug 35 away from the slide rail 31 is above the resin tank 3, and a connecting rod 36 is fixedly connected to the bottom surface of the lug 35. A filter plate 37 is slidably disposed inside the resin tank 3, and the lower end of the connecting rod 36 is fixedly connected to the top surface of the filter plate 37. An outlet is provided below the filter plate 37 in the resin tank 3.

[0044] Specifically, a resin tank 3 is fixedly installed on the top surface of the base plate 1.

[0045] Specifically, the linear motion mechanism includes a second motor 32 and a threaded rod 33. The slide rail 31 is a rectangular frame, and the second motor 32 is mounted on the top surface of the slide rail 31. The threaded rod 33 is rotatably mounted inside the slide rail 31 via a bearing. The output end of the second motor 32 is connected to the threaded rod 33 via a key. The end of the ear plate 34 away from the connecting rod 36 is connected to a threaded block 34. The threaded block 34 is provided with a threaded hole, which is threadedly connected to the threaded rod 33. The threaded block 34 contacts the inner wall of the slide rail 31. Under the limiting of the slide rail 31 and the drive of the threaded rod 34, the threaded block 34 moves up and down.

[0046] By adopting the above technical solution, the filter plate 37 is hollow, which facilitates the sieving of water and resin. The water can fall to the bottom of the resin tank 3 and submerge the filter plate 37, while the resin will fall onto the filter plate 37. After the resin separation is completed, the second motor 32 is turned on, which causes the threaded rod 33 to rotate, thereby causing the threaded block 34 to drive the ear plate 35 to rise. At the same time, the connecting rod 36 drives the filter plate 37 to rise, which facilitates the manual collection of resin on the filter plate 37 for subsequent use and avoids the waste of resin.

[0047] Furthermore, the pneumatic transport pipeline includes an air pump 2 and an air pipe 21. The air pump 2 is connected to one port of the air pipe 21. The discharge pipe 15 is inserted into the wall of the air pipe 21. The discharge pipe 15 is equipped with a shut-off check valve 16 to control the opening and closing. The port of the air pipe 21 away from the air pump 2 is located inside the resin tank 3.

[0048] Specifically, an air pump 2 is fixedly installed on the top surface of the base plate 1.

[0049] Specifically, the shut-off check valve 16 is controlled by a handle, hydraulic or electric means, and when opened, the resin in the mixing tank 12 enters the air pipe 21.

[0050] By adopting the above technical solution, by turning on the air pump 2, air is delivered from the air pipe 21 to the resin tank 3. Then, the shut-off check valve 16 is opened, allowing water and resin to be delivered from the discharge pipe 15 to the air pipe 21. The air pump 2 then blows air to deliver the water and resin in the air pipe 21 to the resin tank 3, which facilitates the rapid filling of water and resin, reduces personnel operation, lowers labor costs and resin filling time. During transportation, the air pump 2 does not come into contact with the resin mixture, so that the resin cannot affect the service life of the air pump 2, and at the same time prevents resin contamination.

[0051] Example 2:

[0052] Based on Example 1, this example applies a water treatment resin blowing and filling device for oilfield steam injection boilers to oilfield steam injection boilers.

[0053] The top surface of the base plate 1 is fixedly provided with the oilfield steam injection boiler body 4, and the top surface of the base plate 1 is fixedly provided with a water pump 42. The water pump 42 is connected to the water outlet of the resin tank 3 through a water pumping pipe 43, and the water pump 42 is connected to the water inlet of the oilfield steam injection boiler body 4 through a delivery pipe 44.

[0054] The oilfield steam injection boiler body 4 itself is existing technology, including structures such as shell, heat exchanger, and heater 41, which are clear to those skilled in the art, so it will not be described in detail here.

[0055] After water treatment is completed, the water pump 42 is turned on, so that the water pumping pipe 43 draws water out of the resin tank 3 and then transports it to the oilfield steam injection boiler body 4 through the delivery pipe 44. The softened water prevents scale from forming in the boiler, thus facilitating the use of the oilfield steam injection boiler body 4.

[0056] Example 3:

[0057] Based on Example 2, this example provides a workflow for an oilfield steam injection boiler water treatment resin blowing and filling device in an oilfield steam injection boiler, including the following steps:

[0058] S1. First, by pouring resin from the feed hopper 13 into the mixing tank 12, and simultaneously connecting the water inlet pipe 14 to an external water pipe, water can be added to the mixing tank 12. Then, the first motor 17 is turned on, causing the rotating shaft 18 to rotate, which in turn causes the stirring rod 19 to rotate, stirring and mixing the water and resin. This ensures that the water and resin are fully mixed and in complete contact before entering the resin tank 3, preventing water stratification and thus softening the water and improving the water treatment effect.

[0059] S2. After the resin-water mixture is completed, the air pump 2 is turned on to deliver air from the air pipe 21 to the resin tank 3. Then, the shut-off check valve 16 is opened to deliver water and resin from the discharge pipe 15 to the air pipe 21. The air pump 2 then blows air to deliver the water and resin in the air pipe 21 to the resin tank 3, which facilitates the rapid filling of water and resin, reduces manual operation, lowers labor costs and resin filling time, and prevents resin contamination.

[0060] S3. Then, the water delivered to the resin tank 3 falls to the bottom of the resin tank 3 and submerges the filter plate 37. The resin falls onto the filter plate 37. After the resin-water mixture is transported, the second motor 32 is turned on, which causes the threaded rod 33 to rotate. This causes the threaded block 34 to drive the ear plate 35 to rise, and the connecting rod 36 to drive the filter plate 37 to rise. This makes it easier for the resin on the filter plate 37 to be collected manually and put back into the mixing tank 12. When the resin has been used up to the number of times it needs to be regenerated, the ion exchange performance of the resin is restored through the resin regeneration equipment.

[0061] S4. After water treatment is completed, turn on the water pump 42 so that the water pumping pipe 43 can draw water out of the resin tank 3 and then transport it from the delivery pipe 44 to the oilfield steam injection boiler body 4. The softened water prevents the boiler from producing scale, thus facilitating the use of the oilfield steam injection boiler body 4.
